- Make their shell files (.cshrc) check where they're coming from. Or give
- them a secure shell which sees who's the parent process; if it's getty
- they're coming in from a modem and you should can 'em.
-
- Something like
-
- #!/bin/sh
-
- ppid=/bin/ps l $$ | awk '$1 !~ /F/ {print $4}'
- if [ "$ppid" = "1" ]; then
- echo "so longer, sucker"
- exit(1)
- else
- exec /bin/csh !*
- fi
-
- or at least along those lines.

- Does your modem report call progress? Like CARRIER 2400, PROTOCOL ALT,
- CONNECT 38400 or whatnot?
